Boundary optimal control of coupled parabolic PDE-ODE systems
(
IFAC Secretariat
, 2014 , Conference Paper)
This paper deals with boundary optimal control problem for coupled parabolic PDEODE systems. The problem is studied using infinite-dimensional state space representation of the coupled PDE-ODE system. Linearization of the ...
Image steganography based on LSBMR using Sobel edge detection
(
IEEE
, 2014 , Conference Paper)
Steganography is the science of embedding confidential data inside data so they can be sent to destination without suspicion. Image-steganography is the most popular type of carrier to hold information. Many algorithms ...
Tensile, hardness, and torsion behavior of welded AA
(
Trans Tech Publications Ltd
, 2014 , Conference Paper)
Tensile, Torsion, and Hardness behavior of welded and un-welded Aluminium Alloy 6061 T6 were investigated. Tests were conducted to evaluate the impact of tungsten Gas Arc welding (TIG) on some of the mechanical properties ...
Numerical investigation of rotating stall characteristics and active stall control in centrifugal compressors
(
American Society of Mechanical Engineers (ASME)
, 2014 , Conference Paper)
This paper focuses on providing better view for the understanding of rotating stall phenomenon in centrifugal compressors by using numerical simulations and presents a study of the role of air injection method in delaying ...
Common-mode voltage control through vector selection in three-to-five phase matrix converter
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Multi-phase matrix converters (more than three phase) are distinctively advantageous as because of reduced per-phase current and unity power factor operation. The electrical motors supplied through these converters do have ...
Retinal image enhancement using Laplacian pyramidal multi-scaling
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Early detection of retinal diseases is important to avoid complications and permanent vision loss. In this paper retinal neovascularization and molecular degeneration has been emphasized. Neovascularization is in form of ...
Numerical simulation and control of rotating stall in a transonic centrifugal compressor
(
Web Portal ASME (American Society of Mechanical Engineers)
, 2014 , Conference Paper)
This study presents a numerical simulation of precursors and characteristics of rotating stall in a centrifugal compressor with vaned diffuser. The aim is to further understand the causes of stall inception, characteristics ...
Numerical study on settlement of piled foundations on homogenous rock
(
Taylor and Francis
, 2014 , Conference Paper)
Settlement behavior of piled foundations on homogenous rock was investigated using an extensive three-dimensional finite element analysis of different piled-foundation models. Effects of pile slenderness ratio, pile spacing, ...
Using a PBL authoring tool to train teachers in designing an online PBL unit
(
Asia-Pacific Society for Computers in Education
, 2014 , Conference Paper)
Problem-based learning (PBL) is proposed as one of the most well-known alternatives to subject-based learning in educating graduates to become independent workers, critical thinkers, problem solvers, lifelong learners, and ...
Geothermal energy extraction from decommissioned petroleum wells
(
International Society for Rock Mechanics
, 2014 , Conference Paper)
Abandoned wells impose enduring liabilities to petroleum companies and/or governments. However, the depth and abundance of abandoned petroleum wells make them an economically attractive source of geothermal energy. Geothermal ...
